A bicycle wheel securing structure (22) includes a shaft member (30), a head member (32), a lever member (34) and a radial expansion structure. The shaft member (30) has first and second end portions (30a, 30b). The head member (32) is coupled at the second end portion (30b). The lever member (34) is operatively mounted to move the shaft member (30) in an axial direction relative to the head member (32) in response to movement of the lever member (34). The radial expansion structure is disposed at the second end portion (30b) and includes an expansion member (44) and the second end portion (30b) of the shaft member (30). The expansion member (44) has a first inclined surface (44a) and the second end portion (30b) of the shaft member (30) has a second inclined surface (40h) that cooperates with the first inclined surface (44a) to radially expand an outer diameter of the radial expansion structure in response to movement of the lever member (34) from a release position to an attachment position. |
